Cara Mengirim Photo/Media Bot Telegram

Ada teman yang bingung bagimana cara kirim photo di bot Telegram, berikut solusinya :

function apiRequestMedia($method, $idchat, $data) {
 $chat_id = $idchat;
 $bot_url = (API_URL);
 $url = $bot_url . $method . "?chat_id=" . $chat_id ;
 $ch = curl_init(); 
 curl_setopt($ch, CURLOPT_HTTPHEADER, array(
     "Content-Type:multipart/form-data"
 ));
 curl_setopt($ch, CURLOPT_URL, $url); 
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
 curl_setopt($ch, CURLOPT_POSTFIELDS, $data); 
 $output = curl_exec($ch);
}

 
$address = "/home/adminxxx/Document/xxx.co.id/bot/a.jpg";
$post_fields = array('caption'   => 'Test Theo',
'photo'     => new CURLFile(realpath($address))
);  
//apiRequestMedia("sendPhoto", $idchat, $post_fields);

Sekian dan terima kasih.
